[1] Transport of nonaqueous phase liquids (NAPLs) in soils is becoming an increasingly serious threat to the environment. Detection and observation of these substances are thus an increasingly important issue. During recent years, studies have used the apparent dielectric constant (K-a) measured by time domain reflectometry (TDR) for determining the saturation of NAPLs (theta(NAPL)) in soils (m(3)

III-V nanowires have been fabricated by metal-organic vapor-phase epitaxy without using Au or other metal particles as a catalyst. Instead, prior to growth, a thin SiOx layer is deposited on the substrates. Wires form on various III-V substrates as well as on Si. They are nontapered in thickness and exhibit a hexagonal cross-section. From high-resolution X-ray diffraction, the epitaxial relation b

We propose time-frequency domain methods for noise estimation and speech enhancement. A speech presence detection method is used to find connected time-frequency regions of speech presence. These regions are used by a noise estimation method and both the speech presence decisions and the noise estimate are used in the speech enhancement method. Different attenuation rules are applied to regions wi

In this thesis Word of Life (Slovo zivota) in the Czech Republic is studied from a sociological perspective with a special focus on the Swedish influence, especially the teachings of Ulf Ekman, on the Czech Word of Life-congregations. Another purpose is to examine if there also is space for domestic interpretations of the theology of the faith-movement and if there is any integration with Czech re

Today the main optimization parameter of digital filters is the filter order. By the aid of two implemented filters we will show that both power and speed can be enhanced if the optimization effort is made on reducing the filter coefficient lengths rather than minimizing the order. Both filters have been designed from the same specification, one as a standard minimum order filter, the other as a f

Through alterations primarily in the penicillin-binding proteins, a non-beta-lactamase-mediated resistance to beta-lactams has evolved in Haemophilus influenzae. The virulence of these chromosomally changed strains has been questioned. To ascertain whether these alterations involve a reduction in virulence of H. influenzae and whether they could be advantageous for the bacterium during amoxicillin

With a simplified model in the Hartree-Fock-Bogoliubov (HFB) approximation, the behavior of weakly bound s(1/2) neutrons in the many-body pair correlation is studied by solving the HFB equation in coordinate space with the correct asymptotic boundary conditions. It is shown that in one-neutron pickup reactions on the even-even neutron-drip-line nuclei, which contain loosely bound s(1/2) neutrons,

Quantum oscillations of the spin conductance through regular and chaotic 2D quantum dots under the varying Rashba spin-orbit interaction and at zero magnetic field have been investigated numerically by summing up the spin evolution matrices for classical transmitting trajectories. The Fourier analysis of these oscillations indicates a strong geometry dependence of the power spectra. The spectra fo

The purpose of this work was to implement the European Protocol on Dosimetry in Mammography in Sweden. The standard average glandular dose, AGD, was measured on 32 mammography units in southern Sweden, according to the European protocol as well as to the Nordic protocol. The most important difference is that the European protocol evaluates the half value layer, HVL, of the X ray beam with the comp

X-ray photoelectron spectroscopy (XPS) was used to study the distribution of elements and main wood components (cellulose and lignin) within the wood and at the bark/wood interface of a living hybrid aspen stem. The hybrid aspen was grown upright in a greenhouse and then tilted at similar to45degrees to induce tension wood formation and upright bending of the stem. The wood between the pith and th

Vehicle design is characterized by a high number of compromises. The special role of human factors in the process is to ensure that the compromises do not occur at the expense of the driver and passengers. Within the automotive industry there is a need for the development of inexpensive and efficient ergonomic tools, facilitating a fast and cost effective car development process as well as discuss

Although trisomy 8 as a sole change is one of the most common chromosomal abnormalities in myeloid malignancies, it is largely unknown if the incidence of this aberration is influenced by other factors of clinical importance. In the present study, the frequencies of isolated +8 in relation to gender, age, previous treatment with chemo- or radiotherapy, and morphologic subtype were ascertained in p

In a retrospective study of 213 patients with high-grade non-Hodgkin's lymphomas clinical stage I, diagnosed 1985-1990, pretreatment prognostic variables and result of treatment were analysed. The median age of the patients was 67 years. Treatment consisted of radiotherapy in 61%, chemotherapy (10%) chemotherapy followed by radiotherapy (23%) and surgery alone (5%) of the patients.

Denna rapport ger en översikt över kulturgeografisk forskning som berör kulturmiljöer i de tre svenska storstadsregionerna under efterkrigstiden. Översikten är strukturerad efter tema snarare än tidsavsnitt eller region. Dessa tema är "Mark och planering", "Stadens funktionsuppdelning och dagligrum", "Geografisk stadsekologi", "Platsen i staden" samt "Segregation och stadsomvandling". Rapporten ha
